3 SPECIFICATION forming part ofLetters Patent No. 432,401, dated July15, 1890.

Application filed F bruary 18,1890. Serial No.-340,97. (No specimens.) 77 To all whom it'may coir/cent;- Bet known that we, ANDERSON GRATZ- andBENJAMIN. GRATZ, both of the city of St.

Louis,in the State of Missouri, have invented F Process of ManufacturingBagging from Jute much inoredesirable; The bagging made duced and placedupon the market ,Very

produce'a bagging from jute butts which will be, far superior to thebagging heretofore made from this article, in that it is lighter in oldarticle. 7

It has been common for many years to treat fabrics with differentchemicals, including ing them fire-proof. The only methods of treating''such fabrics, so far as we are aware, has beenby steepingfor boilingthe fabrics in a chloride of sodium or other chemicalsolution;'"but"'this*method would be wholly-impracticable in themanufactureof bagging from jute butts, owing to the great bulk of thematerial to behandled and the very cheap way in which the goods must bemade. "The total expense of manufacturing bagging from jute butts doesnot" exceed one cent per not exceed three-quarters of one'cent perpound, and if the bagging were steeped or saturated with the chloride ofi sodium it would cost at least one-quarter of onecent per rially to thecost of the product as to interhas-been found to give good result?tically made. l p p In practicing our invention-we use chloride ofsodium, and toavoid thissoaki'ng orsteep- 'ing of the product We haveconductedv many experiments in applying the sol'ution ofychloride ofsodium more different processesof manufacturing this coarse bagging'from jute butts, and after many-trialslhavefdiscovered and adopted theplanlot' 's rinkling the cloth with a solution-of chlorid f sodium,being tion when it is rolled into fight pmk gput away in a, dampcondition. WVe p to apply the solutioiito the goods after, w

the r goods'are on the ccalender and just -before being rolled up a verythoroughgan'd even distribution of the chloride :of sodium through thegoods is obtained. As before 75 I stated, the rolls are stored awayas-they come", a 7 from the calender in a damp condition, produced bythe application of the chloride-of sodium,and the -result is thatachemica l actiontakes place in the tightly-rolled; goods,f8o which verymaterially improveskthe color of, c the article and adds much-to itsvalue, but practically nothing to the cost of itsfproductionl I v We arethus enabled, to produce a very much higher grade ofbagging than ithasbeen possible heretofore to produce'from jute butts.- i l I As anexample of a suitable solution per;
